Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 543,034,315, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 543,034,315 | |
| -1 | -543,034,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 543,034,315.
Example:
1 x 543,034,315 = 543,034,315
and
-1 x -543,034,315 = 543,034,315
Notice both answers equal 543,034,315
With that explanation out of the way, let's continue. Next, we take the number 543,034,315 and divide it by 2:
543,034,315 ÷ 2 = 271,517,157.5
If the quotient is a whole number, then 2 and 271,517,157.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 543,034,315 | |
| -1 | -543,034,315 |
Now, we try dividing 543,034,315 by 3:
543,034,315 ÷ 3 = 181,011,438.3333
If the quotient is a whole number, then 3 and 181,011,438.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 543,034,315 | |
| -1 | -543,034,315 |
Let's try dividing by 4:
543,034,315 ÷ 4 = 135,758,578.75
If the quotient is a whole number, then 4 and 135,758,578.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 543,034,315 | |
| -1 | 543,034,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 148,573 | 742,865 | 2,525,741 | 6,388,639 | 12,628,705 | 31,943,195 | 108,606,863 | 543,034,315 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -148,573 | -742,865 | -2,525,741 | -6,388,639 | -12,628,705 | -31,943,195 | -108,606,863 | -543,034,315 |
